Lebanon’s top Christian cleric urged fractious politicians on Sunday to speed up the formation of a government to allow authorities to prepare for presidential elections due before the end of October.

Lebanon’s Najib Mikati was nominated premier for a fourth time on Thursday after securing the support of 54 of parliament’s 128 lawmakers, including the Iran-backed Hezbollah, in consultations convened by President Michel Aoun.

But with splits running deep among Lebanon’s ruling elite, it is widely believed Mikati will struggle to form a government, spelling political paralysis that could hamper reforms agreed with the International Monetary Fund to unlock aid.

“Again I demand speeding up formation of a national government with the country’s pressing need for it and so that the focus can immediately be on preparations to elect a president who saves the country,” Maronite Patriarch Bechara Boutros Al-Rai said at a sermon on Sunday.

“We call on all parties to cooperate with the premier designate ...,” he added.

Analysts and politicians expect the process of forming a Cabinet to be further complicated by a looming struggle over who will replace Aoun, the Hezbollah-aligned head of state, when his term ends on Oct. 31.
